Problems solved by technology

[0007] The purpose of the present invention is to provide a database access control method and device based on data labels, which is used to improve the database access control technology in the prior art, which can only be protected according to static configuration or dynamic learning strategies. The configuration complexity is high and the security is low, and the database cannot be protected based on data classification and classification labels

Embodiment

[0040] see figure 1 , figure 1 Shown is a flowchart of a data tag-based database access control method provided by an embodiment of the present application. A data tag-based database access control method, comprising the following steps:

[0041] S110: Scan the data in the database according to the preset data feature to obtain the first sensitive data in the database;

[0042] Specifically, according to the preset data features, feature matching is performed on the data inside the database through an active scanning mechanism, so as to obtain the first sensitive data in the database.

[0043] Wherein, the first sensitive data may include customer number, VAT registration address, contact number, resident ID number, license plate number and bank card number.

[0044] In detail, such as the characteristics of the ID card number: it consists of 18 digits, and the first 6 digits are the administrative division code. The 7th to 14th digits are the date of birth code, represent...

Abstract

The invention provides a database access control method and device based on data labels, which relate to the technical field of databases. The method comprises the following steps of scanning data in a database according to preset data features to obtain first sensitive data in the database, classifying and grading the first sensitive data according to preset sensitive data subitems to obtain classification and grading labels, analyzing the first sensitive data in each classification and grading label to divide the sensitive grade of each classification and grading label, formulating an access control rule according to the sensitivity level, if the visitor accesses the database, acquiring the identity of the visitor and an access request, and if the visitor identity and the access request conform to the access control rule, allowing the visitor to enter the database. Aiming at the identity and the access request of the visitor, the access of the visitor is controlled according to the classification and grading label, and different first sensitive data are specifically classified and protected, so that the database is better protected.

Description

technical field [0001] The present invention relates to the technical field of databases, and in particular, to a method and device for database access control based on data tags. Background technique [0002] Existing database access control technologies have great shortcomings in terms of control granularity, configuration complexity, and security: [0003] In terms of control granularity, the access control mechanism of the database itself is mainly based on user identity, and only supports the control of instance and table names, and cannot be controlled based on detailed SQL instructions and classification and grading results. [0004] In terms of configuration complexity, the access control mechanism of the database itself is mainly set by DBA personnel through the command line, which is highly complex. [0005] In terms of security, the database's own access control mechanism is configured by the DBA, and the DBA's authority cannot be effectively controlled, and ther...
